Hello,
I was eager to resolve it, so I tried to upgrade to VDP 6.0.4 in the hope it is tested against current vCenter version. Unfortuntately, the release info talks about kernel patch which should be part of the installation ISO, but it isn't there. and yes, the upgrade did not succeed.
Next step was to abandon current backups and remove VDP completely (deleted from inventory, removed from vCenter registry through MOB methods invocation and removed from vCenter Web Client folder, all according to KBs) and to install it from scratch, step by step according to installation guide. Not even this works: the OVF deployment and configuration wizard aparently succeed, but after next reboot, it is stuck at 70% of "VDP: configuring appliance" task for 8 hours. Web interface to VDP is still just the configuration wizard. Of course, there is no VDP icon in vCenter Web client and in the MOB registry is only one extension registered (com.vmware.vdp2.config is there as expected, but com.vmware.vdp2 is missing).
So it seems VDP is not an option for me anymore. There were many problems with it in all previous versions, maybe now it's the right time to abandon it completely. I am writing my story here, just in case somebody knows how to push the VDP configuration to the end and make it usable. Or am I the last one who is still using this piece of .... ?
